Matrix System of Equations

Question (a)

Question (a)

Solve the system.  Write the matrix equation on your own paper.
5x + 8y = -12
3x + 5y = -7

• (1, -10)

• No solution

• (-4, 1)

• (1, 10)

Solve:
-4x - 5y - z = 18
-2x - 5y - 2z = 12
-2x + 5y + 2z = 4

• (4, 0, -2)

• (-4, 0, -2)

• Many Solutions

• I did not get any of the answers above so I am assuming none of the above.

Two linear equations with the same set of variables

• system of equations

• function

• association

• correlation
